Reir is a land of plains and animals who fare well there, including unicorns and the wild centaurs. (The centaurs live on the western side.) The humans there tend to be plainsmen, and some of the best riders on Tu. Reir is the finest place to find breeds of unicorns, though unicorns can be found everywhere, and their unicorn horn ivory is very prized. Reir has a human king and a council that has representatives of fifteen great tribes...seven human ones, and eight centaur ones. Their coat-of-arms/shield/banner is a unicorn and a Centaur, touching outstretched hooves. Thiamim is a land of deserts, of the roc and the basilisk and the sphynx. Rodut is a bare land with few inhabitants, animal or human.
